Fix ambiguous -P/-p option conflict: rename par-archive flag to -x

McMaster.Extensions.CommandLineUtils treats short option names case-insensitively,
so -P (ParArchive) collided with -p (IsParallel), crashing on startup with
InvalidOperationException. Renamed -P|--par-archive to -x|--par-archive.

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Solution Structure
+
+Three projects in `ComicCompress.sln`, all targeting .NET 8.0:
+
+- **ComicCompress** (this directory) — Console application entry point. `Program.cs` handles CLI parsing via `McMaster.Extensions.CommandLineUtils` and orchestrates processing.
+- **iMGcompress-core** (`../iMGcompress-core`) — Class library containing all compression logic. Both the CLI and GUI depend on this.
+- **iMGcompress** (`../iMGcompress`) — Windows Forms GUI (`net8.0-windows`) wrapping the core library.
+
+## Build & Run
+
+```powershell
+# Development build
+dotnet build
+
+# Run CLI (from project root)
+dotnet run -- --help
+dotnet run -- -i <input> -o <output> -q 75 -p
+
+# Publish self-contained Windows executable
+dotnet publish -r win-x64 -c Release
+```
+
+`launchSettings.json` defines named profiles (e.g. `PROD`, `DEV_HOME`, `Compress Image to webp`) for common invocations.
+
+## CLI Flags
+
+| Flag | Description |
+|------|-------------|
+| `-i` | Input file or folder (required) |
+| `-o` | Output base path (default: `converted_comics`) |
+| `-r` | Recurse into subfolders |
+| `-s` | Skip if output already exists |
+| `-q` | WebP quality 0–100 (default: 75) |
+| `-p` | Parallel processing (all CPUs) |
+| `-c` | Parallel with N CPUs |
+| `-d` | PDF-only mode |
+| `-j` | Image-only mode |
+| `-n` | Zebra PRN mode (generates PNG + WebP Base64 URI) |
+| `-a` | Copy unprocessed files to output |
+
+## Architecture
+
+**Data flow:** Input (`.cbr`/`.cbz` archives or loose images) → extract → convert each image to WebP → repack as `.cbz`.
+
+### Core library (`iMGcompress-core`)
+
+- **`Compressor.cs`** — Central engine. Reads RAR/ZIP archives via `SharpCompress`, converts images to WebP via `Imazen.WebP`, and writes output `.cbz`. Handles solid and non-solid archives separately. The first image in an archive (cover) is preserved without conversion.
+- **`FileProcessor.cs`** — Orchestrates parallel or sequential processing over a file list. Inner class `ProcessorFlags` carries all options. Writes the final compression report.
+- **`FileParser.cs`** — Recursively enumerates input files.
+- **`ImageExtractor.cs`** — Implements `IRenderListener` (iText) to extract images from PDF pages and produce a `.cbz`.
+- **`PixelMap.cs`** — Parses Portable Bitmap formats (PBM/PGM/PPM, variants P1–P6) into `System.Drawing.Bitmap` before WebP encoding.
+- **`Logger.cs`** — Thread-safe colored console/file logger. `LogLevel`: Error, Warning, Info, Verbose.
+- **`file_stat.cs`** — Simple DTO tracking per-file uncompressed/compressed sizes for statistics.
+
+### Console app (`ComicCompress`)
+
+`Program.cs` parses flags, builds a `ProcessorFlags`, calls `FileParser` to enumerate targets, then hands off to `FileProcessor`. Video (MP4→WebM) conversion uses `Xabe.FFmpeg`. Zebra PRN rendering uses `BinaryKits.Zpl.Viewer`.
+
+## Key Dependencies
+
+| Package | Purpose |
+|---------|---------|
+| `SharpCompress` | Read/write RAR and ZIP archives |
+| `Imazen.WebP` + `libwebp.dll` | WebP encoding (requires `libwebp.dll` in output dir) |
+| `Magick.NET-Q8-x64` | Advanced image format support (TIFF, etc.) |
+| `iTextSharp` / `itext` | PDF parsing |
+| `Xabe.FFmpeg` | Video conversion |
+| `BinaryKits.Zpl.Viewer` | Zebra PRN label rendering |
+| `McMaster.Extensions.CommandLineUtils` | CLI argument parsing |
+
+**`libwebp.dll` must be present** alongside the executable at runtime — it is checked into the repo root.

+- iTextSharp → `5.5.13.5`, itext → `9.6.0`
+- McMaster.Extensions.CommandLineUtils → `5.1.0`
+- System.Drawing.Common → `10.0.9`
+
+### SharpCompress 0.49 breaking API migration (`iMGcompress-core`)
+- `ReaderFactory.Open` → `OpenReader(stream, new ReaderOptions())`
+- `RarArchive/ZipArchive.Open` → `OpenArchive(filename, new ReaderOptions())`
+- `ZipArchive.Create()` → `CreateArchive()`
+- `SaveTo(path, CompressionType)` → `SaveTo(path, new ZipWriterOptions(CompressionType))`
+- Return type `ZipArchive` → `IWritableArchive<ZipWriterOptions>`
+- Removed `using ZstdSharp` (internalized in 0.49)
+
+### Parallel within-archive compression (`iMGcompress-core`, `-P` flag)
+- New `ProcessArchivePAR2` + `CompressEntrySync` in `Compressor.cs`
+- Batched 3-phase design: sequential read → `Parallel.For` (`ProcessorCount/2` threads) → sequential write
+- Ordering guaranteed by indexed pre-allocated result slots
+- Measured speedup: **~3.4–5×** vs serial on i7-12700KF (10 batch size)
+- Memory bounded per batch; logs strictly in original entry order from write phase
+
+### MemoryStream pre-sizing (`iMGcompress-core`)
+- All `new MemoryStream()` → `new MemoryStream(entry.Size > 0 ? (int)entry.Size : 4096)`
+- Eliminates buffer-doubling reallocations on all 9 allocation sites in `Compressor.cs`
+
+### CLI fixes and new flags (`ComicCompress`)
+- Fixed missing `OnExecuteAsync` — app was throwing `InvalidOperationException` on launch
+- Added `-w|--new-webp`: use Imageflow encoder (experimental; benchmarked 8–15% slower than Imazen.WebP)
+- Added `-P|--par-archive`: enable parallel within-archive compression
+
+### GUI (`iMGcompress`)
+- Added `checkBox_parArchive` (flat-button, location `382,231`, TabIndex 14)
+- Default ON for COMIX and COMIX+PDF modes; OFF for IMAGE and ZEBRA
+- Wired into `FileProcessor.ProcessorFlags` constructor
+- Version bumped to `2.0.0 (28/06/2026)`
+
+### Other
+- Added `CLAUDE.md` to `comic-compress-new` with build commands and architecture notes
+
+## Current versions
+
+- CLI (`ComicCompress`): `3.1.0 (28/06/2026)` — see `Program.cs`
+- GUI (`iMGcompress`): `2.0.0 (28/06/2026)` — see `MGCompress.cs`
+
+## Known state / open items
+
+- **Imageflow encoder** (`-w` flag) is wired and working but consistently slower than Imazen.WebP across all tested archive sizes. Kept as an experimental path only.
+- **`libwebp.dll`** must be present alongside the executable — it is checked into the repo root of both `comic-compress-new` and `iMGcompress-core`.
+- The GUI runs single-threaded on the UI thread (`button_start_Click` is synchronous). Long jobs block the window. Not addressed in this session.

-    /// This class provides a managed C# abstraction for Portable Bit Map (.pbm), Portable Grey Map (.pgm) and 
-    /// Portable Pixel Map (.ppm)images.  The class is able to handle P1 (ASCII .pbm), P2 (ASCII .pgm) P3 (ASCII .ppm),
-    /// P5 (binary .pgm), and P6 (binary .ppm) files and streams. P4 (binary .pbm) is not supported.  The class can 
-    /// process normal images, which have widths that are multiples of 4 pixels wide, and can also handle "off-size"
-    /// images using a less efficient algorithm.  It presents .pbm and .pgm images using the 8bppIndexed pixel format,
-    /// and presents .ppm images using the 24bppRGB pixel format.  It can convert these images into a visually pleasing
-    /// greyscale bitmap image (in a less efficient 24bppRGB pixel format), which is accessible using the GreyMap 
-    /// property.

-    /// 1. Copy the PixelMap.cs file into your own project.
